Bit of both. I have a small corten steel water bowl with a bubbler in the middle, for the sound as much as anything. Does take a good deal of leaf sluicing, and occasionally the local pigeons use it to dip their scavenged bread in. Broadly worth it though - I just clean it when I top it up after evaporation gets to it, and I just top it up when I am watering plants.
